BOX

Filed Oct. 17, 19?? and bottom of the Patented Oct. 29, 1929 UNITED STATES FRANK J'. SCHLEICHER, 0F ST. LOUIS, MISSOURI BOX Application led October l?, 1987. Serial No. 226,727.

'lhis invention relates to a paper or cardboard box of oval or circular shape having a continuously curved side wall for the top and bottom portion of the box respectively,

5 and secured to the top and bottom in the novel manner herein disclosed.

An object of the invention is to improve the construction of such a box by providing a side wall for the top portion and a side 10 wall for the bottom portion, each of said walls being composed of a single piece of material having its ends overlapping, and improved means for strengthening the connection of the overlapping ends with the top box, respectivel Other objects will appear from t e following description, reference being made to the drawing, in which Fig. 1 is a bottom plan view of my im- 20 proved box with part of the outer sheet of the bottom broken away to Show clearly the construction by which the side walls aie attached to the bottom and top of the box, re spectively.

Fig. 2 is a side elevation of my im roved box showing the top partly telescope upon the bottom.

Fig. 3 is a cross sectional view of a part of the box.

Fig. 4 is a perspective view showing the connection between the ends of the side wall.

Fig. 5 is a perspective view further illus trating the'connection of the ends of the side wall with the top or bottom of the box.

Fig. 6 is a sectional view on the line 6 6 of Fig. 5.

The top and bottom ofjny improved box, whether the side walls be `made of oval or other circular form, are of duplicate construe- 40 tion except that the side wall of the top encloses a slightly larger area than the side wall of the bottom. Thus, when the top is placed on the bottom, the side wall of the top closely surrounds the side Wall of the bottom of the box. Since the top and bottom are of duplicate construction with this exception, a description of one applies also to the other and like ieference numerals are applied to simi- )arts of the top and bottom of the box.

lar The top and bottom of the box each comrises an outer section 1 of cardbtmrd or simiar material.

There is an inner section 2 for the top and bottom of the box of slightly' smaller area than the area of the outer section l. 'lhe edge of 'the section 2 is oval or circular throughout its circumference in order to deline the shape of the side walls.

The Side wall of the bottom and the top of the box, res iectively, comprises an elon- "ated strip 3 o cardboard, or the like, of a ength slightly greater than the distance around the inner section 2. Ata distance from one longitudinal edge ot' this strip 3 a score line 4 is formed nearly throughout the length of said strip and parallel with its edge. 'lhat part of the strip etween the score line 4 and the adjacent edge is provided with notches 5 extending to said score line.` These notches are approximately V-shaped and form between t iem V-shaped tongues 6. 'lhe tongues 6 formed by these notches 5 are bent laterally at right angles along the score lille 4 and are extended between and glued to the inner and outer bottom and top sections 1 and 2, So that the walls 3 bear closely' against the edges of said inner bottom and top sections 2.,

The ends of each side wall 3 are secured together in overlapping arrangement and in a novel manner to form the connection of the strength necessary to withstand the strains and stresses to which the box may be sul jected. This is accomplished by removing to the depth of the score line 4 a portion of the outer side of one end of the wall 3 to form a portion 7 of reduced thickness. The adiacent full thickness end of the wall 3 overlaps the portion 7 and fills the notch at the outer side of said portion 7. Similarly, the tongue (i, extending from the portion 7, is of reduced thickness and is overlapped by the tongue 6 of full thickness extending from the overlapping portion of the other end of the wa l.

When the parts are assembled in this rela` tionshi in which the tongues 6 extend between t e outer portions 1 and the inner portions 2 of the top and bottom of the box` and in which the relatively thin part 7 of the side. wall is overlapped by the opposite end of the side wall, and in which the tongue 6 of reduced thickness is overlapped by the tongue b on the adjacent end of the side wall, the parts are secured together by glue previously applied to at least one of everytwo contacting surfaces, and by pressure upon the outer and inner portions 1 and 2. Thus the tongues 6 are glued to the parts 1 and 2;' the part 7 is glued to the end of the wall 3 which it overlaps, and the two overlapping tongues 6 are glued together and to the parts 1 and 2, respectively.

In the case of a box embodying the invention,'wherein the walls 3 are not perfectly circular in shape it is preferred that the overlapping ends be arranged in such relationship th'at the joints 8 of the wall 3 of the top and bottom portions of the box cannot be brought opposite each other. Thus, a continuous portion of each wall 3 strengthens the joint of the other wall.

By reference to .Figs 4 and 5 it is clear enough that the part 7 .which overlaps the adjacent end of the wall is bent inwardly so that at the oint 8 the ends of the wall are in endwise a utting contact and that the outer surfaces of both ends of the wall are flush or in alinement with each other. The portion 7 is not an end of the wall, but is an elongation of an end of the wall. Accordingly, there is no outside shoulder at the joint 8. Thus, since there is no outside shoulder at the joint 8', the lid of the box which is of the same construction will telescope smoothly over the box proper and may obtain close contact with the box wall throughout the outside circumference of the box and the inside of the lid. The advantages of having the ends of the wall smooth and even or in alinement with each other are many and will be clear to those skilled in the art. Accordingly by my present invention I obtain a good connection of the ends of the box walls and also obtain a construction in which the outer surfaces of the ends of the wall are in alinement forming a smooth and continuous outer surface allaround the box. The joint 8 consists of endwise abutting portions of the walls.

From this it must be seen that I have produced a box, having continuously curved side walls for the top and bottom portions of the box, assembled by novel construction so that the box may be manufactured economically, and will possess the strength needed for the uses to which the box is to be applied.

I claim:

1. A box comprising an inside bottomforming sheet having a continuously curved edge, a side wall for said box comprising an elongated strip having V-shaped tongues extending from one edge and bent inwardly andeglued against the under side of said bottom sheet, one end of said strip being of reduced thickness and overlapping and glued to the inner side of the adjacent end of full thickness, and having a V-shaped tongue of reduced thickness overlapped by the V- shaped tongue of full thickness of the adjacent end andsecured thereto by glue, and an outside bottom-forming sheet glued to said tonguesand having its edges extending beyond said wall.

2. A box including a bottom sheet, a side wall for said sheet comprising an elongated strip scored longitudinally on a line spaced inwardly from one edge thereof, the strip for the full distance between thev scoring and the said edge being notched to form tongues, one end portion of the wall strip being reduced in thickness by the removal of the outer side thereof to the depth of the scoring and from the top edge through the tongue occurring at the end of the s trip, the ends of the strip being secured to each other with the reduced end portion including its tongue receiving and overlapping the remaining vend portion and its tongue, and means for securing the tongues to the said bottom sheet.

3. A box including a bottom sheet, a side wall for said sheet comprising an elongated strip scored longitudinally on a line spaced inwardly from one edge thereof, the strip for the full distance between the scoring and the said edge being cut to form tongues, said wall strip extending around the edge of said sheet and having its ends abutting endwise, an elongation on one end of said strip overlapping and extending along the inner side of the other end of said strip above and supported by one of said tongues von said other end, and theends of said strip being secured together, and means for securing the tongues to said bottom sheet.

4. A box comprising a bottom wall, a side wall comprising an elongated strip scored longitudinally on a line spaced inwardly from one edge thereof, the strip for the full distance between the scoring and the said edge being cnt to form tongues which are y secured against the underside of said bottom,

said wall strip extending around the edge of said bottom and having its ends abutting endwise and forming a joint in which the outer surfaces of the endwise abutting ends are approximately even and flush with each other, an elongation on one end of said strip overlapping and extending along the inner side of the other end of said strip and attached thereto, and an outer section attached to said tongues and having its outer marginal portionvextending beyond the outer side of.

said wall and guarding and shielding the lower portion of said joint at the ends of said strip and also guarding and shielding the line of union of said tongues with said strip throughout the circumference of the box.
